JENNIFER FINER STAFF WRITER T ime has done little to fade the memories not only of Holocaust survivors but also the American troops who liberated the camps. Fifty years ago this month World War II came to an end, and Americans first entered the Nazi death camps. Unprepared for what they would find inside, many did what they could to document the horror. Some took pictures. Others relied on a pen and paper to tell the stories of the Holocaust. One photographer talked as an assistant captured every word on an Army typewriter. Five decades later, his original impressions are unaltered. "Later in the evening at a meeting, our captain told us of a slave-labor camp near us where it was believed some 200 people had been burned that morning," he wrote. "That seemed as impossible to us as did the other stories." The pictures, the words and the memories of these libera- tors will forever remind the world of the Holocaust.
